Comparative study on the anatomy and palynology of the three variety of Vitis vinifera varity (family Vitaceae)

Abstract

Morphological and anatomical evaluation on three varieties of Vitis vinifera (Trerash, Rash meri and Baidhaw) commonly known as grape vine was reported. The samples were prepared in a mixture containing 95% of alcohol and glacial acetic acid. The result revealed differences among the varieties ranging from morphological to aesthetic features of the leaf. Although, starch grains, druses and raphid crystals were present in all the varieties, the shape of the stem, petiole, midrib, lamina and margin were anatomically different as well as the presence of trichomes among the varieties. The microstructure of the leaf epidermis was investigated using light microscope (LM) and scanning electron microscope (SEM) which confirmed the polygonal shape of the leaf epidermal cells and the anticlinal walls which were straight and arched from the surface view. The structure of the stomata apparatus was present only in the abaxial epidermis and anomocyte type. SEM was used to investigate the pollen grains tricolporat and sub prolate often known as prolate-spheroidal. The flower was bisexual having size ranging between 4 to 5 mm.

Review of the Traditional Uses, Phytochemistry, and Pharmacological Activities of Rhoicissus Species (Vitaceae)

“…This known group of flowering plants usually features erect, prostrate, woody climbers, often with swollen or jointed nodes and herbaceous vines, or small succulent trees [ 21 , 24 , 28 , 29 ]. Vitaceae are readily distinguished from other angiosperm families by their unique seed morphology, inflorescences as cyme, corymb, or panicle, and leaf-opposed tendrils, enabling the family to be the most successful climbers in tropical and temperate forests [ 23 , 25 , 29 , 30 ]. The stomata apertures in the epidermis are bounded by two guard cells which primarily allow the rapid movement of carbon dioxide, water vapour, and oxygen in and out of the leaf [ 29 ].…”

The flowers are small, greenish, and inconspicuous, with a ring-like or lobed disc [ 28 , 31 ].…”

Application and implication of scanning electron microscopy for evaluation of palyno‐morphological features of Vitaceae from Pakistan

“…Tre rash , Rash meri were spheroidal to oval and unaperturate. Colpi were absent (Najmaddin, Hussin, & Maideen, 2011). The extension of developmental studies beyond what is currently known for Vitaceae, the morphological and anatomical and palynological characters will allow for a more stable classification of the family and advance the evolutionary aspects of Vitaceae and Rosids as a whole (Ickert‐Bond, Gerrath, Posluszny, & Wen, 2015).…”

Taxonomic study of pollen grains for five species of Fabaceae Family

“…Measurements were captured under both 40X and 100X magnification. The thickness of the wall (exine) was gauged in line with the approach delineated by [22].…”
